Countersink drill bit set with hexagonal shank, five-edge cutting geometry, and carbon steel construction Key benefits Better grip and control: Hexagonal shank design prevents slipping in the chuck and gives a secure, comfortable hold for each drilling and countersinking operation. Stable handling reduces the risk of errors and increases user safety, especially with tougher materials. Smooth, ready-to-use chamfers: Five-edge cutting geometry produces clean chamfers and removes wood burrs efficiently so that no additional sanding or filing is needed in most cases. Delivers consistent deburring across different wood types. Durable performance: Made from robust carbon steel for high wear resistance and reliable operation over repeated use. Built to maintain cutting performance and deliver consistent results over time. Versatile for woodworking: Designed for multiple woodworking tasks—precise edge finishing, creating tight tenon connections, and drilling larger component holes—so the set adapts to common shop and DIY requirements.
